'Check access' will return 'OK' if you set up permissions correctly.

OSV15.png
18. Afterward, set up a network. Choose 'Fixed Network' , 'Floating Network' and 'Default Number Of IP Addresses' .

You can set up network in two ways. You can find more information about the configuration here.
We will set up the network without a floating IP address as presented on the following screen.
Additionally, choose a quantity of IP addresses assigned to a product by typing it into 'Default Number Of IP Addresses' .

OSV16.png
19. At this step you can set up backups.

Mark the 'Backups Routing' checkbox if you want to replace oldest backup with newest one when backups file limit is reached.
Afterward, enter a limit of backup files into 'Default Backups Files Limit' .

OSV17.png
20. Mark a security group from 'Use Security Groups' and select 'Console Type' .

If you wish to use SSH keys, leave 'Inject SSH Key' marked (virtualization has to support the 'Inject File' feature).
In order to use passwords for your VM, leave 'Password Management' marked (virtualization has to support the 'Set Admin Pass' feature).
Please make sure, that virtualization used by you supports mentioned actions.
Full list of supported features can be found here.
Important: It is recommended to leave 'Delete SSH Private Key' marked.
The following types of console can be chosen: 'VNC', 'RDP', 'SPICE' and 'Serial' .

OSV17 1.png
21. You can also take advantage of the dedicated Volume and set it as the location of your Virtual Machine Disk,

To do so, make sure to tick the Use Volumes checkbox and enter the desired number into the Default Volume Size field.
Note that once this option is enabled, your clients will no longer have access to the Backup and Rescue functions, so you may as well leave the respective fields empty.

OSV17 2.png
22. Finish through selecting features available at the client area.

Mark the checkbox next to a feature in order to enable it. Press 'Save Changes' when you are done.

VPS With Predefined Resources

Our module allows you to offer OpenStack VPS to your clients in two ways, with either predefined or configurable resources.

In this section we will show you configuration of VPS with predefined resources.
Detailed information about configuration of VPS with resources chosen by a client can be found here.

23. Select a 'Default Flavor' and 'Default VM Image' .

'Default Flavour' defined resources assigned to a VM while 'Default VM Image' allows you to choose the VM image used to create a new VM.

OSV19.png
Congratulations! You have just finished the installation and configuration of the module with predefined resources.

VPS With Configurable Resources

24. Preparing VPS with configurable options consists of pressing 'Generate default' as shown on the following screen.

It will prepare default configurable options which can be afterward easily edited as described in this article.
Important Configurable option 'flavor|Flavor' will be overwritten by 'disc|Disc' , 'ram|RAM' and 'vcpus|VCPUs' .
Therefore, you can solve this in three ways:

  • Remove 'disc|Disc' , 'ram|RAM' and 'vcpus|VCPUs' configurable option and rely completely on 'flavor|Flavor' .
  • Remove 'disc|Disc' and 'vcpus|VCPUs' , and allow 'flavor|Flavor' being overwritten by 'ram|RAM' (multiple combinations allowed here).
  • Remove 'flavor|Flavor' and rely completely on 'disc|Disc' , 'ram|RAM' and 'vcpus|VCPUs' .

Note: The second and the third options results in creation of a new flavor on your server each time a new order is made.

Custom Config Scripts

25. In this area, you can write a custom script using Cloud-Init and arrange it to be executed on newly created VMs.

This way you can automate your work instead of making all kinds of specific images for specific tasks manually.

Important notes:

  • Scripts can be written in standards like Bash or YAML.
  • Initial scripts have to be supported by VPS operating system to be executed properly.
  • Scripts should be used only by advanced users. The incorrect usage of the scripts may damage your system!
OSV44.png
On the example below, we will show an examplary script responsible for setting the password to 'newpass01' for the Ubuntu root user.

You can achieve it by writing:

chpasswd:
 list: |
 ubuntu:newpass01
 expire:False
OSV45.png
You can configure scripts in the same format, but for clients' individual choice when ordering the product.

All you need to do is add a new configurable option and assign it to the OpenStack VPS product.
Note: these scripts are executed regardless of the script specified in the module settings.
The easiest way is through the edition of existing 'Configurable options for the OpenStack VPS' group, and adding the new configurable option there.
For example, if you want to offer the pre-installed PHP version depending on a client's choice, you can add a new option named script_PHP|PHP version and then define multiple options, like on the screenshot below:

OSV46.png
Afterward, your clients can choose during the ordering process:
OSV47.png

Using this method, you can perform assorted actions on newly created machines, e.g.: modifying files, preinstalling & preconfiguring software, executing any statements that would normally be executed via the terminal.

The general rule is that configurable option names should begin with script_prefix to be recognized as containing a custom script.
Then, choices under the option have their own names which are matched with a name of existing file with the corresponding script under the yourWHMCS/modules/servers/OpenStackVPS/scripts path.
Note that files with scripts have to have exactly extension corresponding to the given entries in the configurable options.

In the example above, there are two options: php5.yml and php7.yml, therefore it makes the module read corresponding files:

  • modules/servers/OpenStackVPS/scripts/php5.yml

or

  • modules/servers/OpenStackVPS/scripts/php7.yml

You can add many scripts in the exact way.

Management

OpenStack VPS For WHMCS allows your customers to manage their OpenStack VPS via the client area in your WHMCS system.

You can monitor and manage each product from your WHMCS admin area.
1. Configurable options which enables you to view current VPS resources and change VPS specifications through changing configurable options and pressing 'Change Package' .
2. Module commands enables you to manage VPS status.
3. Here you can find VPS details and refresh them through pressing the 'Refresh Details' icon.
4. Scheduled tasks status can be found in this table.
5. In marked custom fields you can find IDs of VM and private flavor.

OSV24.png
If you decided to select the Use Volumes feature, you will see an additional section named Volumes.
OSV24 1.png

Ordering

Owing to configurable options, you are able to offer a product which your clients can tailor according to their needs.

Additionally, you are able to set up pricing for each configurable option, which make your offer even more competitive.
Important: VPS is not created immediately after ordering 'Create' . Therefore, it is wise to inform your clients about the delay.

OSV25.png

Client Area

Client area interface of OpenStack VPS should look like the one on the screen below. As you can see, the control panel contains useful options needed for managing a VPS.

Module allows your customers to easily start/stop, pause/unpause, resume, soft reboot, hard reboot and reset network of their servers through pressing the specific button.
Clients can also rebuild the server, access noVNC console, create a backup and view scheduled tasks.
At 'Tasks' your customers can view all requested tasks that was not yet completed.
Each task has additional information bounded to them, like a type of task, attempts to perform tasks or a last returned response.

OSV26.png

Volumes

In case your OpenStack VPS is running with the Use Volumes option, the client area may look a bit different. It will now include an additional section named Volumes
OSV26 1.png

Rebuild

The rebuild feature allows your clients to change a server image.

Press the 'Rebuild' button as shown on the following screen in order to move to the rebuild page.

OSV27.png
To reinstall your server, choose an image and confirm through clicking on 'Rebuild' .
OSV28.png

Rescue Mode

The rescue mode provides a mechanism for a VM access even in case the VM's image renders the instance inaccessible - e.g. if instance's filesystem becomes corrupted.

The rescue VM will be launched to permit the user to fix their VM.

OSV48.png

Before you continue please note that the rescue VM will be set up with the same network configuration as the real VM.
Moreover, a new root password will be generated and the VM status will change to 'RESCUE'.
The new VM will also have a rescue image as the primary filesystem and the secondary filesystem would be the original VM's primary filesystem.

OSV49.png
When you want to disable the rescue mode, click the 'Unrescue' buton. TheVM status will then also return to 'ACTIVE'.
OSV50.png

Backups

Your customers can also create a backup of VPS. To do so, press the 'Backups' button.
OSV31.png
Now, choose a backup name and click 'Backup Now' .
OSV32.png
To restore a VPS from backup, simply press the 'Restore' button next to it.

As you may notice on the following screen, presented earlier the 'First Backup' backup was replaced with the 'New Backup' .
It was caused by a backup routing feature which was triggered by reaching the backups file limit.

OSV33.png

noVNC Console

One of the most interesting functionality is a noVNC console where your clients can remotely manage their server.

To access it, simply click on the 'Console' button.

OSV29.png
noVNC is a browser based VNC client. It was implemented using HTML5 Canvas and WebSockets.
OSV30.png

SSH Keys

Due to a limitation in WHMCS product create process, OpenStack VPS For WHMCS generates SSH key pair automatically.

The public SSH key is automatically injected into a VM while the private key can be downloaded from the client area.
In order to download Unix private SSH key press 'Download Private Key' .
You can easily convert your private Unix key(.rsa) to a private PuTTY key(.ppk) using 'PuTTYgen' .

OSV34.png
Public SSH key in other hand, can be downloaded as many times as your client will need it.

Press 'Download Public Key' as shown on the following screen to save it on your disk.

OSV35.png

Network Configuration Cases

OpenStack VPS For WHMCS allows you to set up two types of network.

The first one is a network without a floating IP address.
To set up this type of network, choose 'Public' as 'Fixed Network' and 'Disabled' as 'Floating Network' .
On the following screen you can view an exemplary topology of such network.

OSV36.png
The second type of network is the network with a floating IP address.

Select 'Shared Network' as 'Fixed Network' and 'Public' as 'Floating Network' .

OSV37.png

Configurable Options

In case that standard configuration is not fitting your needs, you can adjust it through configurable options.

To do so, go to 'Setup' 'Products/Services' 'Configurable Option' and press the edit button next to a configurable option used by your product.
Its name is 'Configurable options for your_product_name' .

OSV38.png
Here you can view the products that this configurable option group is assigned to.

Now we will show you how to edit options. Let's say that you want to add an option to order VPS with 8GB (8192 MB) RAM.
To do so, edit 'ram|RAM' by pressing the edit button as shown on the screen below.

OSV39.png
You will see a popup window, so make sure that your browser will not block it.

To add a new option, enter it in a textbox under all other options. If you want to replace it with an option you currently have, simply edit its text box.
Next, press 'Save Changes' .

OSV40.png

Management of Billing

When you combine OpenStack VPS For WHMCS with Advanced Billing For WHMCS, you will be able to set up additional billing options.

Module allows you to charge your customers based on the server resources used by them.
Note: Advanced Billing currently supports only API prior V3 (OpenStack Ocata). A new compatibility will be added soon.

OSV42.png
With Advanced Billing module, you can also display your customers the current server resource usage, their cost, usage history and charts.

Tips

1. Due to some requests may take time to be completed, we implemented 'Scheduled Tasks' .

Tasks visible at 'Scheduled Tasks' are subsequently performed by a cron job.
Full list of tasks supported by 'Scheduled Tasks' are: create, terminate, change package, remove IP address and remove backup.

2. Important: module has to use admin endpoints instead of public endpoints.

In properly configured OpenStack server, wget from WHMCS server should be able to get any data from any admin endpoint.
Sample successfull requests:

wget openstack:9292
--2014-03-31 09:35:24-- http://openstack:9292/
